I'd add one more point specific to vehicle (or other safety-related) applications: if it keeps changing, it's shit. I shouldn't have to hunt around for where that control went today any more than I should have to hunt around for where it went the first time. That is why I think touchscreens with tactile feedback don't solve this problem, even though they're cool in general. That customizability is worthless because the controls shouldn't be changing anyway. Just put in real buttons, knobs, and so on.
